Show HN: An application to stop the barking of dogs with separation anxiety

I created a software application that helps dogs with separation anxiety. The application creates audio log of dog's barking, so the user can find out exactly how much and when the dog has been barking. It allows to easily record sound clips that will be played back to the dog whenever barking is detected. The dog will recognize his owner's voice and calm down.

The program has been in beta testing for over two years. It works surprisingly well and the feedback we have received has been very positive. We released a public version a few months back and it can be downloaded from http://www.digitaldogsitter.com.

Please, tell me what you think. I'd appreciate any thoughts on the idea in general, the software itself, business model, or the web site.
